Description
DNS managed zone DNSSEC key-signing keys should not use RSASHA1. Domain Name System Security Extensions (DNSSEC) algorithm numbers may be used in CERT RRs. Zone signing (DNSSEC) and transaction security mechanisms (SIG(0) and TSIG) make use of particular subsets of these algorithms. The key-signing key algorithm should be strong, and RSASHA1 is no longer considered secure. Use it only for compatibility reasons.
How to fix?
Where dnssec_config.default_key_specs.key_type
is set to keySigning
, set dnssec_config.default_key_specs.algorithm
attribute to secure algorithm, such as rsasha512
.
Example configuration
resource "google_dns_managed_zone" "allowed_3" {
name = "peering-zone-402a3"
dns_name = "dns.google."
description = "Example private DNS Service Directory zone"
dnssec_config {
state = "on"
default_key_specs {
algorithm = "rsasha512"
key_type = "keySigning"
key_length = 2048
}
default_key_specs {
algorithm = "rsasha512"
key_type = "zoneSigning"
key_length = 1024
}
}
}
